@fredericknyagaHi,1) It may be an issue with APN (ACCESS POINT NAME) Settings on your device (Internet and MMS settings ) and/ or what you select when you first put your giffgaff sim card into your device.

2)You have not stated what type of device you have.

When posting queries relating to function of your device, it would be useful to people trying to help you - and more beneficial to you in the long-run - if you provided info as to exactly what type of device you have.

That way, people that have experience of using your particular type of device should be able to provide you with help that is more specific to your particular device - otherwise, all you will get is general advice applicable to different devices.

3) Firstly, if you have a smartphone, when you first put the giffgaff sim card in your smartphone it may have given you a list of mobile networks and asked you to select one. Sometimes 'giffgaff' is given as an option, so obviously you should select that. However sometimes it does not give giffgaff as an option but it should still give o2 as an option if a list appears. Do NOT choose o2 because you won't get Internet connection, just select 'CANCEL', then enter the APN (Access Point Name) settings for Internet and MMS manually, save them and then select to activate those SPECIFIC settings .

5)This website link will take you to different giffgaff website pages re: Internet: https://giffgaff.com/support/calls-and-internet/internet-and-data**************************************************6) *MANUAL ROAM:If you don't get Internet connection and you are using correct settings for Internet and MMSs, you can do a MANUAL ROAM (manual search for network.) To do that:a) Switch off MOBILE DATA connection.b) Should be something on your device which says something like ''Network Operator'. Click on that. Phone may automatically do manual search for available mobile network signals. However, if phone does not do so automatically, then look for something that says similiar to 'Search Networks... Scan for all available networks.' Select that. Phone should then do manual search for available network signals.c) Select the appropriate mobile network. [If you are given o2 as an option, Select that as giffgaff operates off o2 Network. (N. B., When you first put giffgaff Sim card in phone, if you Select 'o2' it will not work. )]d) Switch Mobile Data connection back ON.

(***You can also try selecting WRONG network first and then when phone says it can't connect to that network, do manual search again and then select correct mobile network.************************************************7) *REBOOT: IF there is still a problem, try switching phone off, then switch it back on again after a few minutes. **************************************************

8) If you are using correct Internet and MMS settings and find that there is any FURTHER problem in future , try switching Mobile Data off and do manual search for network to reconnect to correct mobile network.
